WebNov 23, 2024 · pH of pure water For pure water the concentration of [H + ] and [OH –] ions are same. That means, [H + ] = [OH –] So, from equation (i) we can write, K w = [H +] 2 As K w = 1.00 X 10 -14 mol 2 dm -6 [H +] 2 = 1.00 X 10 -14 mol 2 dm -6 Thus [H +] = 1.00 X 10 -7 mol dm -3 And pH = – log 10 [H +] = – log 10 (1.00 X 10 -7) So pH = 7
WebFeb 15, 2024 · mass of water: assume 1000 g (we must know the density of the solution to find its exact value) The molality of the solution is (5.8 mol) ÷ (1.0 kg) = 5.8 m. Using the value of K b from the table, the boiling point will be raised by (0.514 K mol –1 kg) × (5.8 mol kg –1) = 3.0 K, so the boiling point will be 103° C. metathesaurus definitionWebLiquid water (H 2 O) at 25 °C.
